Itbed by Design it

itbed is only a bed when you want it to be! The itbed is made from 7 mm thick cardboard that is folded like an accordion. In one step the itbed can be collapsed into an easily portable bundle making the cardboard bed an ideal solution for guest beds or frequent movers. The zigzag profile of the itbed, reminiscent of a house of cards, is stabilized from head to foot by two lengths of webbing.
